Quick question as to whether anyone can anyone either link me to a tutorial or explain in steps how to create one of those cave entrances where you walk in to active the loading screen? I did a quick search of the forums and couldn't find anything along the lines of this, but if this has been asked before, sorry. Any and all help is appreciated and thanks in advance.

Filter out automatic in the doors section. Use one of those.

Thanks, nice and straightforward.
